The Simple Machines: Lever & Pulleys set is designed to introduce students to the scientific concepts associated with two types of simple machines: levers and pulleys. Students are provided with the opportunity to acquire skills using a hands-on, inquiry-based approach to information and concepts. Working cooperatively, students are encouraged to interact with each other as they build, investigate, discuss, and evaluate scientific principles in action. ... more
The Teacher's Guide provides the information and resources needed to build students' understanding of scientific concepts and channel their inquiries into active and meaningful learning experiences. Extension activities that can be used to explore the concepts more deeply are also included.

Set includes 178 K'NEX® parts – enough to build 8 fully-functioning replicas of real-world machines, one at a time. Supports 2 to 3 students working as a team. Primary 3-6. Building instructions and comprehensive teacher's guide aligned to Science, Technology, Engineering and Math Standards are included. Packaged in a strong storage tray with snap-on lid.
